To all whom t mdg/fconcem:

Be it known that I, MENNo .Kuna citi?y zen of the United States, residingatz-Mount Hope, in the county of Holmes and State of'.` Ohio, have invented new` and usefuly Im# provements in Rotary Internal-Combustion Engines, of which the following is a sp'ecifijy cation. y

This invention relates torotary internal y combustion engines, and-*one vobject .is to ,l provide a constructionv more eiicientfthan those heretofore "employed, in engines ofthe type indicated.

A further object is toprovide certainv novel Y means for mountin'gffa` plurality of plungers," these plungers beingcarrie'dffin pairs by La plurality of .annular` members mounted in an annular chamber within a fly wheel, this annular chamber affording space for the compressionfofa charge betweencertain of the plungerscarried by oppositely located rings.

A still furthv r object is tov provideyin an 'y engine ofthe type'indicated a lcasing mem`" ber provided with inletand exhaust ports,"

a fly wheel rotatablewithinsaid casing and provided rwith, an annular chamber, aplurality of independently mountedgring mem#` bers located withinv the chamber, eachv of said rin g members carrying ,a pair of plungers, lthe 'lplungers being oppositely located, [a stationary -annular y coreV carried between flanged [portions of the casingkand cop-` erating withy said ring members, and means forholding one of thefr'ing members, stationary during the yfiring of thechargeand the powerstroke of the'pistons carried` byl the other of said ring members.

vWiththe foregoing andother objects iny view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter described 'and claimed. n

` In the accompanying Vdrawings:
